Re: using (in-readtable) to select a readtable

Hi!

My opinion is that two approaches are incompatible. Problem is the same I have noted before: (in-package) form leads to implicit (and sometimes unpredictable) change of current readtable in SLIME. I think more discussion is required. First I thought I could suggest a mode switch which alters behaviour of (in-readtable), but it is implicit and this is bad. So second suggestion is the following: 1. Create new form, say (in-readtbl) which changes readtable, but does not affect *readtable-alist* 2. Create variable, *lock-readtable-alist*. If it is true, error is signalled on attempt to alter *readtable-alist* 3. Display readtable name on modeline.
